Solution Overview

Problem

Compression garments are difficult to don, particularly for lower legs, as they require both hands and bending forward, making it laborious to apply the correct compression force.

Innovation Solution

A compression garment design featuring an elongated stretchable sleeve with a compression part and closing parts, including a gauge system that indicates proper stretch for compression force, allowing easy donning with one hand by using a cover that reveals the gauge when sufficient stretch is reached, and a continuous compression part for even pressure distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a compression garment is designed to provide proper compression force, then the compression function is improved, but the difficulty of donning the garment increases

Engineering Contradiction:
Improvecompression forceVSAvoiddonning difficulty
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The compression garment is divided into distinct functional segments: a compression part that provides compression force, a closing part that secures the garment, and a cover with window that indicates proper stretching. This segmentation allows each part to perform its specific function independently, making the overall donning process easier while ensuring proper compression.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cover with window acts as a feedback mechanism, visually indicating when the compression garment has been stretched sufficiently during donning. This feedback helps the user understand when to stop stretching, ensuring proper compression force is achieved without excessive effort or discomfort.

Inventive Principle:
Principle #23Feedback

2Reliability

If both hands are used to don the compression garment, then the compression force can be properly applied, but the operation becomes laborious and requires bending forward

Engineering Contradiction:
Improvecompression forceVSAvoidoperation simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The compression garment is designed to be donned with one hand by utilizing the elastic properties of the material and the strategic placement of the closing part. The garment essentially serves itself by allowing the user to pull it on without requiring two hands to manipulate and secure it properly.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The closing part is pre-positioned on the compression garment in a way that allows it to be engaged automatically during the one-handed donning process. This preliminary arrangement eliminates the need for complex manual manipulation and bending forward that would be required if both hands were needed.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the compression part is stretched to achieve proper compression, then the compression function is improved, but the user cannot easily determine when sufficient stretch has been reached

Engineering Contradiction:
Improvecompression forceVSAvoidstretch indication
Core Design Contradiction:
ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

The cover with window provides visual feedback through a clear indicator (the window itself acting as a visual marker) that changes state when the compression garment is stretched sufficiently. This visual change makes it immediately apparent to the user when proper stretching has been achieved, eliminating uncertainty about the compression level.

Inventive Principle:
Principle #32Color changes

AI summary

A compression garment comprises a compression part, at least one closing part (3), a cover and at least one gauge (71, 72). The at least one gauge (71, 72) is applied to the at least one closing part (3) for indicating when a proper amount of compression force in the compression part has been reached, by indicating the amount of stretch of said at least one closing part. The cover (6) covers at least partly the at least one closing part (3), such that the at least one gauge (71, 72) is covered by the cover (6) if sufficient stretch has not been reached and is uncovered if sufficient stretch has been reached. Alternatively, the cover (6) comprises a window (73) such that the at least one gauge (71, 72) is covered by the cover (6) if sufficient stretch has not been reached and is visible in the window (73) if sufficient stretch has been reached, or is visible in the window (73) if sufficient stretch has not been reached and is covered if sufficient stretch has been reached.
